RUBBER-MODIFIED STYRENIC RESIN COMPOSITION AND PRODUCING METHOD

摘要

PROBLEM TO BE SOLVED: To provide a method for efficiently producing, without blending, a rubber-modified styrenic resin suitably used for large-size blow molding which is free from a gelled product and has an excellent physical property balance among flowing property, melt tension and impact resistance, and a resin composition obtained by the method. SOLUTION: The method for producing the rubber-modified styrenic resin composition comprises using, based on 100 pts.wt. in total of an aromatic monovinyl compound and a rubber-like component, 30×10-4to 160×10-4pts.wt. of a polyfunctional vinyl compound, 50×10-4to 260×10-4pts.wt. of a polymerization initiator, and 100×10-4to 2000×10-4pts.wt. of silicone oil.
